A liquid of density $\displaystyle 750 \mathrm{kgm}^{-3}$ flows smoothly through a horizontal pipe that tapers in cross-sectional area from $\displaystyle \mathrm{A}_1=1.2 \times 10^{-2} \mathrm{~m}^2$ to $\displaystyle \mathrm{A}_2=\frac{\mathrm{A}_1}{2}$. The pressure difference between the wide and narrow sections of the pipe is $\displaystyle 4500$ Pa. The rate of flow of liquid is \_\_\_\_ $\displaystyle \times 10^{-3} \mathrm{~m}^3 \mathrm{~s}^{-1}$.
